Objective:To explore the construction and application of an evidence-based practice plan for early postoperative activity in postoperative patients with large area cerebral infarction.Methods:Ninety-six postoperative patients with large area cerebral infarction admitted to Wenzhou Central Hospital from July 2021 to April 2023 were selected as the study subjects for a Clinical trial. They were divided into the control group (48 cases) and the observation group (48 cases) by random number table method. The control group received routine postoperative care for neurosurgery, while the observation group received evidence-based systematic early activity training. Both groups were followed up until 1 month after the patient was discharged from the hospital. The time of postoperative hospitalization, hospitalization expenses, vital signs and pain investigation 48 h after surgery, daily living ability before intervention and 7 d, 1 month after discharge, neurological function before intervention and 7 d and 1 month after surgery, and complications during follow-up between the two groups were compared.Results:In the control group, there were 29 males and 19 females, with an average age of 43-67(56.87 ± 1.76) years. In the observation group, there were 31 males and 17 females, with an average age of 43-68 (57.02 ± 1.82) years. The postoperative hospital stay in the observation group was (6.87 ± 0.65) d, in the control group was (9.06 ± 0.72) d, the difference between them was significant ( t=15.64, P<0.05). 48 hours after surgery, the heart rate, breathing rate and mean arterial pressure in the observation group were (71.65 ± 0, 45) times/min, (14.76 ± 0.36) times/min and (76.98 ± 5.65) mmHg(1 mmHg=0.133 kPa), which were different with those in the control group, (82.76 ± 2.65) times/min, (18.76 ± 2.87) times/min and (93.76 ± 5.93) mmHg ( t=28.64, 9.58 and 14.19, all P<0.05). Seven days after discharge, the score of Activities of Daily Living and the National Institutes of Health Neurological Impairment Scale in the observation group were (84.65 ± 2.45) and (23.65 ± 2.65), which were different than the (79.76 ± 1.97) and (28.54 ± 2.73) in the control group ( t=10.26, 8.91, both P<0.05). A month after discharge, the score of Activities of Daily Living and the National Institutes of Health Neurological Impairment Scale in the observation group were (95.45 ± 1.43) and (18.65 ± 1.98), while in the control group were (87.87 ± 1.39) and (21.54 ± 2.76), the difference between them were significant ( t=26.33, 5.90, both P<0.05). The total incidence of complications such as postoperative bleeding, postoperative infection and hypoxemia in the observation group was 20.83% (10/48), which was significant lower than the 68.75% (33/48) in the control group ( χ2=22.28, P<0.05). Conclusions:Evidence-based systematic early activity training could significantly alleviate postoperative pain in patients with large area cerebral infarction after surgery, improve their daily living ability and neurological function, further effectively shorten their hospitalization time, and reduce the occurrence of complications.

Objective:To evaluate the effects of different types of psychological interventions on the fear of cancer recurrence through a network Meta-analysis.Methods:Randomized controlled trials on the effects of different types of psychological interventions on the fear of cancer recurrence were retrieved from PubMed, PsycINFO, Web of Science, The Cochrane Library, Embase, EBSCO, China Biomedical Literature Database, CNKI, Wanfang Database and Vip Database. The retrieval period was from the establishment of the database to December, 31 2022. Two researchers conducted literature screening, extraction and quality evaluation, and used Stata14.0 software to conduct network Meta-analysis.Results:A total of 29 pieces of research involving 3 068 cancer patients and 11 psychological intervention measures. The results of network Meta-analysis showed that narrative therapy, PERMA(Positive, Engagement, Relationship, Meaning, Accomplishment) happiness theory model, acceptance and commitment therapy and cognitive behavior therapy had statistically significant differences in the intervention effect on the fear of cancer recurrence compared with conventional nursing ( SMD values were -1.93--0.83, all P<0.05); there was no significant difference among narrative therapy, PERMA happiness model, acceptance and commitment therapy and gratitude-expansion behavior theory (all P>0.05). The results of the cumulative probability map showed the best intervention was narrative therapy. Conclusions:The results of this study suggest that narrative therapy, acceptance and commitment therapy, and cognitive behavior therapy may be effective psychological intervention measures to improve the fear of cancer recurrence. However, more studies are still needed for further verification.

BACKGROUND:Plastic as a durable,inexpensive,easy to manufacture organic synthetic polymer materials are widely used.At the same time,plastic resistance to high temperatures,acid and alkali resistance,corrosion-resistant properties make it difficult to degrade in nature,and ultimately forming a huge number of microplastic pollution threatening human health. OBJECTIVE:To investigate the effects of microplastic exposure on growth and development and hepatic lipid metabolism in mice. METHODS:Twenty C57BL/6J male mice were adaptively fed for one week,and then randomly divided into normal and microplastic groups(n=10 per group).Mice in the normal group were given a normal diet and water,for 4 weeks.Mice in the microplastic group were given a normal diet and free drinking of microplastic(polystyrene)water with a concentration of 1 000 μg/L,for 4 weeks.At 2 and 4 weeks of drinking,body mass and grip strength,blood lipids and liver and kidney function,ultrasonic morphology and pathological morphology of liver and lipid deposition were detected. RESULTS AND CONCLUSION:(1)With the extension of time,the body mass of mice in the two groups gradually increased,and the body mass of mice in the microplastic group was greater than that in the normal group after 2,4 weeks of drinking water(P<0.05).With the extension of time,the grip strength of mice in the normal group gradually increased,and the grip strength of mice in the microplastic group first decreased and then increased,and the grip strength of mice in the microplastic group was lower than that in the normal group after drinking water for 4 weeks(P<0.05).(2)Liver ultrasound examination showed that compared with the normal group,the ultrasonic echo signal of the liver in the microplastic group was enhanced after 2 and 4 weeks of drinking water.(3)Hematoxylin-eosin staining showed that the morphology of liver cells in the microplastic group did not change significantly after 2 and 4 weeks of drinking water,but inflammatory cell infiltration could be seen.Oil red O staining showed that obvious lipid deposition was observed in the liver of microplastic group after 2 and 4 weeks of drinking water.(4)Compared with the normal group,the levels of serum high density lipoprotein cholesterol,triacylglycerol,and aspartate aminotransferase in the microplastic group were decreased after 2 weeks of drinking water(P<0.05),and the serum triacylglycerol concentration was decreased after 4 weeks of drinking water(P<0.05).(5)These findings confirm that microplastics may cause weight gain,loss of physical strength,and abnormal hepatic lipid metabolism in mice.

Objective: To explore the clinical efficacy of Xiaoshuan enteric-coated capsule (XSECC) in treating cerebral infarction and its potential mechanism of action. Methods: Patients with acute ischemic stroke (AIS) of the qi deficiency and blood stasis type were randomly assigned to the control and observation groups. They were evaluated using the National Institutes of Health Stroke Scale (NIHSS), Activities of Daily Living (ADL), Hachinskilnchemic Scale (HIS), Barthel Index (BI), clinical efficacy scores, and TCM syndrome scores on days 0, 14, 30, and 90. Furthermore, VEGF and BDNF levels were measured on days 30 and 90. Finally, we analyzed the changes in each scale score and vascular neurological factor in both groups. Results: After 14 days of treatment, the difference values in NIHSS, ADL, and BI were higher, and TCM syndrome and clinical efficacy scores were increased in the observation group compared with those of the control group (all P < .05). After 30 days, the NIHSS, ADL, HIS, and TCM syndrome scores were decreased compared with those of the control group, while BI and clinical efficacy scores were increased (all P < .05). After 90 days, the difference value in ADL was higher, and TCM syndrome score was increased in the observation group compared with that of the control group (P = .047, P = .005, respectively). The levels of VEGF and BDNF were higher in the observation group than in the control group on days 14, 30, and 90 (all P < .05). VEGF and BDNF levels on day 0 were associated with prognosis of patients with AIS; therefore, they have a predictive value for the prognosis of acute cerebral infarction. Conclusions XSECC therapy can improve clinical outcomes in patients with acute and recurrent cerebral infarctions. Its mechanism of action may be associated with the secretion of VEGF and BDNF.

Objective:To explore the impact of digital technology in constructing a three-dimensional (3D) symmetry reference plane (SRP) for esthetic restoration of anterior teeth and to evaluate its clinical applicability.Methods:A cross-sectional study was conducted from February to May 2024, involving 20 patients [11 males and 9 females, aged (36.8±11.4) years] who underwent anterior esthetic restorations at the Department of Stomatology, People′s Hospital of Ningxia Hui Autonomous Region. Symmetrical reference planes of patients′ 3D facial models were constructed using three different algorithms: weighted Procrustes analysis (WPA), Procrustes analysis (PA) based on the ontology-mirror correlation method, and iterative closest point (ICP). The SRP defined by an associate chief physician served as the control (true-value group). The angular errors between each algorithm group and the true-value group were compared. The optimal algorithm was selected and combined with a three-dimensional digital smile design (DSD) to create virtual patients, followed by designing anterior restorations. The visual analogue scale (VAS) was used by patients to score the aesthetic restoration results of the conventional design (control group) and the algorithm-based design (algorithm group).Results:The angular errors of the WPA, PA, and ICP groups were 1.43°±0.66°, 1.82°±0.88°, and 4.74°±2.03° respectively, with statistically significant differences among the groups ( F=41.10, P<0.001). Pairwise comparisons showed that the WPA group had significantly smaller angular errors compared to the PA and ICP groups ( P<0.05). The VAS scores for aesthetic restoration were significantly higher in the algorithm group (8.09±0.74) compared to the control group (6.30±1.38) ( t=-5.49, P<0.001). Conclusions:The SRP constructed using the WPA algorithm demonstrated minimal angular error when compared to the expert-defined SRP and is considered the optimal choice in clinical practice, yielding high patient satisfaction.

Background In the Global Burden of Disease research, it has been found that atmospheric fine particulate matter (PM_2.5) pollution significantly harms human health. Currently, there is limited research on polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) that exhibit high toxicity effects in PM_2.5 . Objective By studying the spatiotemporal distribution and variation characteristics of PCDD/Fs in PM_2.5 in Pudong area of Shanghai, to assess the associated population health risk. Methods This study set up 28 sampling points in Pudong area. One sample of PM_2.5 was collected during winter (February 2022) and summer (July 2022) at each site, with a sampling period lasting 24 h. The concentration of PM_2.5 was measured by membrane filter method, and the content of 17 kinds of 2,3,7,8-substituted chlorinated PCDD/Fs in the samples was analyzed using isotope dilution. Seasonal variations (winter and summer) in the concentrations of PM_2.5 and PCDD/Fs were evaluated, sources of PCDD/Fs pollution were tracing by principal component analysis, and health risks to the population from respiratory exposure to PCDD/Fs were estimated by VLIER-HUMAAN model. Results The PM_2.5 concentrations in the 28 samples ranged from 10 to 126 μg·m⁻³, while the concentrations of PCDD/Fs in PM_2.5 ranged from 58 to 2625 fg·m⁻³. The concentration of PM_2.5 during winter (11-126 μg·m⁻³) was higher than that during summer (10-60 μg·m⁻³). The concentration range of PCDD/Fs in winter was from 58 to 2625 fg·m⁻³, which corresponded to a range of toxic equivalent quantity (WHO-TEQ) concentration from 2.99 to 40.97 fg·m⁻³ when taking World Health Organization's toxic equivalency factor (WHO-TEQ); the concentration range of PCDD/Fs in summer was from 72 to 446 fg·m⁻³, which corresponded to a range of WHO-TEQ concentration from 2.66 to 16.61 fg·m⁻³. This range in summer was significantly lower than that observed in winter. The results of principal component analysis revealed that waste incineration was the primary source of PCDD/Fs in winter PM_2.5 in the area, whereas traffic emissions emerged as the main source in summer. The assessment of Pudong residents' respiratory exposure to PCDD/Fs in PM_2.5 showed significantly higher exposure of children in summer and winter than that of adults, indicating higher susceptibility of children to air pollutants. Both the hazard ratios (HR) for children and adults were below 1, while the cancer risks (CR) ranged from 8.41×10⁻⁸ to 2.35×10⁻⁶. Notably, during winter, the CR at 4 locations slightly exceeds 1×10⁻⁶, indicating a potential carcinogenic risk. Conclusion The overall pollution level of PCDD/Fs in PM_2.5 in Pudong area is relatively low, but it shows clear seasonal patterns. Waste incineration and traffic are the main sources of PCDD/Fs in PM_2.5 in the area. Although the cancer risk of exposure to PCDD/Fs in PM_2.5 for children or adults is relatively low, there is a certain risk at some locations in winter, necessitating additional monitoring and control.

Background and objective Different degrees of self-transcendence exist in lung cancer patients,which can stimulate patients'self-awareness and promote them to face negative events in life positively,thus improving pa-tients'quality of life and treatment outcomes.However,there are few reports on self-transcendence in lung cancer patients in China,and the related influencing factors have not yet been clarified.This study aims to investigate the current situation of self-transcendence in lung cancer patients and explore its risk factors,so as to provide a theoretical basis for clinical intervention decision-making.Methods 243 lung cancer patients who were admitted to the Department of Lung Cancer Center of West China Hospital,Sichuan University from September 2023 to February 2024 were enrolled as the study subjects;general infor-mation questionnaire,self-transcendence scale,Herth hope scale and social support scale were used for the investigation.The influencing factors related to self-transcendence of lung cancer patients were analyzed.Results The total mean score of self-transcendence in lung cancer patients was(44.73±8.94);the total mean score of hope level was(37.60±4.98),and the total mean score of social support was(41.31±7.27).Self-transcendence was positively correlated with hope level and social support(P＜0.001,P＜0.001).Education,hope level and social support were influencing factors of self-transcendence in lung cancer pa-tients(P＜0.05,P＜0.001,P＜0.05).Conclusion Self-transcendence in lung cancer patients was at a low level and was influenced by hope level and social support.Healthcare professionals should pay attention to improving the hope level of lung cancer pa-tients,carrying out targeted psychological interventions,and at the same time guiding them to enhance the perception of social support,so as to promote the realization of self-transcendence in patients.

Objective To explore the polymorphism and distribution of apolipoprotein E(ApoE)gene in patients with hyperlipidemia.Methods A total of 370 hyperlipidemia patients diagnosed at Hangzhou Ninth People's Hospital from October 2023 to June 2024 were selected.Gene polymorphism was detected in the blood samples of the patients using fluorescence polymerase chain reaction,and the distribution of gene polymorphism among different genders and age groups within this population was compared.Results ①The polymorphism distribution of the two genetic loci(ApoE 388T＞C and ApoE 526C＞T)in the studied sample population conforms to Hardy-Weinberg equilibrium,indicating that it is representative of the population;②Among the 370 patients,the distribution of the ApoE gene was as follows:E3/E3(66.49％),E3/E4(20.27％),E2/E3(8.65％),E2/E4(1.89％),E2/E2(1.35％),and E4/E4(1.35％).The proportion of the patient population carrying the E4 allele was about 1.88 times higher than that of those carrying the E2 allele;③The distribution differences of ApoE gene polymorphism were not related to the patients'gender and age(P＞0.05).Conclusion The distribution of ApoE gene polymorphism among hyperlipidemia patients at a hospital in Hangzhou is uneven and is not related to gender or age groups.Therefore,it is recommended to prioritize the detection of ApoE gene in patients before using statin medications to assess treatment effectiveness.

Objective:To study the biological role and related mechanism of autophagy in acute lung injury (ALI) of hemorrhagic shock mice.Methods:According to random number table method, wild-type male C57BL/6 mice were divided into control group, ALI group, rapamycin group and 3-methyladenine (3-MA) group, with 8 mice in each group. Light chain 3 (LC3) gene knockout mice with C57BL/6 background were divided into LC3 knockout group and LC3 knockout+ALI group, with 8 mice in each group. Control group, ALI group, LC3 knockout group, LC3 knockout+ALI group were intraperitoneally injected with 2 mL/kg normal saline, rapamycin group was intraperitoneally injected with 3 mg/kg autophagy activator rapamycin, 3-MA group was intraperitoneally injected with 15 mg/kg autophagy inhibitor 3-MA, all of which were given for 3 consecutive days. 2 hours after the last administration, the hemorrhagic shock induced ALI model was established. 24 hours after modeling, the lung index was calculated. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of lung tissue and lung injury score was performed. The expressions of autophagy genes LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in lung tissue were detected by Western blotting. The contents of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and malondialdehyde (MDA) in lung tissue were detected according to the steps of the kit.Results:Compared with the control group, the lung tissue structure was destroyed and exudation increased, lung index, lung injury score, the expressions of LC3-Ⅱ/LC3-Ⅰ, Beclin-1, and the contents of TNF-α, IL-6 and MDA in lung tissue significantly increased in the ALI group. Compared with the ALI group, the structural damage and exudation of lung tissue were reduced in the rapamycin group, lung index, lung injury score and the contents of TNF-α, IL-6 and MDA in lung tissue decreased, while the expressions of LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in lung tissue increased [lung index: (7.56±0.39)% vs. (9.12±0.59)%, lung injury score: 3.04±0.58 vs. 9.32±2.14, TNF-α (ng/mg): 1.85±0.32 vs. 3.51±0.62, IL-6 (ng/mg): 1.61±0.32 vs. 2.52±0.44, MDA (nmol/mg): 1.03±0.16 vs. 1.88±0.24, LC3-Ⅱ/LC3-Ⅰ: 1.21±0.12 vs. 0.39±0.05, Beclin-1/β-actin: 1.10±0.12 vs. 0.58±0.06, all P < 0.05], while lung tissue structure damage was aggravated and exudation was further increased in the 3-MA group, lung index, lung injury score and the contents of TNF-α, IL-6 and MDA in lung tissue increased, the expressions of LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in lung tissue decreased [lung index: (10.44±0.62)% vs. (9.12±0.59)%, lung injury score: 11.59±2.28 vs. 9.32±2.14, TNF-α (ng/mg): 4.77±0.71 vs. 3.51±0.62, IL-6 (ng/mg): 3.44±0.52 vs. 2.52±0.44, MDA (nmol/mg): 2.71±0.42 vs. 1.88±0.24, LC3-Ⅱ/LC3-Ⅰ: 0.25±0.04 vs. 0.39±0.05, Beclin-1/β-actin: 0.21±0.03 vs. 0.58±0.06, all P < 0.05]. Lung index, lung injury score and the contents of TNF-α, IL-6 and MDA in lung tissue of LC3 knockout ALI mice were higher than those of wild-type ALI mice [lung index: (10.44±0.75)% vs. (9.12±0.59)%, lung injury score: 12.41±2.86 vs. 9.32±2.14, TNF-α (ng/mg): 4.85±0.72 vs. 3.51±0.62, IL-6 (ng/mg): 3.28±0.51 vs. 2.52±0.44, MDA (nmol/mg): 2.75±0.41 vs. 1.88±0.24, all P < 0.05]. Conclusion:Autophagy plays a protective role in ALI of hemorrhagic shock mice, and the related molecular mechanism is the inhibition of inflammatory response and oxidative stress response.
